make sure the antenna signal is set to "cable". go to "MENU" "CHANNEL" AUTO CHANNEL MEMORY" "SIGNAL TYPE CABLE". then scan the channels into memory. if you have satellite or cable box hooked to your tv and you're using channel 3 o 4 and it's set to "AIR" it will not be able to find that channel since everything converted to digital signals. but if you set all your channels to "CABLE" your tv will work. I had the same problem of tv going to blank screen after a few minutes, now mine is working fine. I did NOT replace any board. I hope this works for you. Let me know.

After the screen goes black, do you still have sound or you have none but a blank screen? If you have no picture and sound does the power LED in front of the tv indicate that the set is on, or does it go into standby? Please provide this info so that I can help you with your problem.

Most likely you have a bad back lamp. Most times when this occurs, the screen will come on for a second or two then go off. Replacing a back lamp isn't a job for do it your selfers. It will involve completely disassembly of the LCD panel.

The best way to get you dvd out of the side slot without scratching it is to set the t.v. on a soft surface screen side down. (Carpet works great) Then remove all the screws from the back of the t.v. including the mount stand and take off the 2 panels on the back of the t.v.. One will be in the middle use a flat head screwdriver and lift upwards on the side nearest to the screw, the other on will be in the top left corner do the same here. Then you will want to unhook the wires from the motherboard (they will be bundled) do this by pulling gently on the connecter head (do this as evenly as possible to avoid damaging the pins) remove both connector heads then take the whole back of the t.v. off. After all that you can easily use the white plastic manual dvd release lever. I hope that helps some of you that got this poorly built product. If RCA was thinking about the customer when building this product they would have made a panel right over the dvd player and that would have saved a lot of hassel of course doing what I've suggested will most likely void your warranty and then they wouldn't get to make as much money off you. By the way their customer service is out of Japan and good luck getting anywhere with that.

I have a new power/inverter board for a L32HD32D RCA 32" flat screen LCD TV. Make offer, 1-907-225-2337 I'll ship it USPS in the box it came in.LS2HD32 CEG379B CAJAID, CAJA4465 1114363 are some numbers on the package it came in. You might try LPS#1 on the ribbon cables & their video board connection for the LCD by opening the back 4x5" pannel in the middle & clean reinstall them ? That's what fixed my TV, maybe. So I don't need the board now. It's only about a 5 minute job to clean the 2 ribbon cables.Sincerely Bitdog
